    Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

    Abstract: The invention is related to a disposable contact lens comprising a top coating which is made of a hydrophilic polymeric material including dangling hydrophilic polymer chains covalently linked to the hydrophilic polymeric material through oligo-caprolactone linkages susceptible to enzymatic degradation in the eyes. The top coating is stable to lens processing/storage and confers lubricity to the lens. However, it slowly is degraded during the lens wear due to the action of enzymes (e.g., Lipase) in tear film. The loss in lubricity will be experienced as a drop in comfort for the lens wearer and thereby serves as the built-in compliance features of the disposable contact lens.

    Abstract: The instant invention pertains to a method for producing contact lenses with improved oxidative stability of Carotenoids in the contact lens. The method of the invention involves adding a vitamine E material into a contact lens in an amount sufficient to reduce oxidative degradation of Carotenoids in the lens by at least about 30% in comparison with an identical contact lens without the vitamin E material.

    Abstract: The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a water-soluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.
